If you visit the Arctic or Antarctic areas in the winter you will experience the polar night, which means that the sun doesn't rise above the horizon. Here is the same text in Swahili:
Ukitembelea maeneo ya Aktiki na Antaktiki msimu wa baridi utapata tajriba ya usiku wa pola, ambayo ina maana kuwa jua halichomozi juu ya upeo wa macho.
